Dude, not trying to sound rude, but can you please avoid passing judgements without having sufficient information.
Permanent residence is a long drawn process, it takes months, if not years to process an application.
However, in those months, the life of an applicant goes on. He can switch a job, get married, have kids, etc etc.
And when circumstances change, the applicant has to reach out to VO to update the information.
So, to answer your half informed comment: I was not married when I initially applied in Dec 2014, got married to my long time gf this year and hence I had to add her to my application..
